Title: Origin of the high-frequency contributions to the dielectric loss in supercooled liquids. Author: Hensel-Bielowka S, Paluch M. Journal: Phys Rev Lett; 2002 Jul 08; 89(2):025704. PubMed ID: 12097007. Abstract: Dielectric loss spectra of four different glass formers revealing either beta relaxation or excess wing are presented. We compare the effect of pressure and temperature on the mentioned processes. Our findings suggest that the excess wing and the beta relaxation cannot be treated on the same footing.[Abstract] [Full Text] [Related] [New Search]
